like new york, like london has, have congestion pricing so it's not a free good. make people who use the car pay for it and tilt the balance of our infrastructure funding using some of those funds to rebuild our public transit infrastructure. as you know, i've traveled into new york all the time and travel into canada all the time. my wife always reminds me to difference of traveling into pearson airport versus the new york, our greatest city in the world, airports. we've got to put a little more money. we know airplanes according to a whole range of recent studies are big economic generators. act on the same plane as our high-tech industry clusters. we need to rebuild our airports, invest in our public transit as well as keeping our roads going. but let's pay for the roads. >> ken, i see you nodding. do you think there are some things that rank higher than other things or should this be done as a portfolio, that there are a lot of things that need to be fixed? richard made a reference to the $2 trillion number to get our infrastructure on a national level up to a reliable point. >>
